pLVX-Tet3G is a regulator vector that stably expresses the Tet-On® 3G transactivator protein, as part of any Lenti-X™ Tet-On 3G Inducible Expression System. The Lenti-X Tet-On 3G Inducible Expression Systems allow for the lentiviral delivery and inducible expression of your gene of interest in a wide variety of mammalian cells. Target cells that express the Tet-On 3G transactivator protein from pLVX-Tet3G and contain a gene of interest under the control of a pTRE3G promoter will express high levels of your gene, only when cultured in the presence of doxycycline.
